The character of Charlie Dixon was played by Tim Guinee in the original pilot. His scenes were re-shot with Dean Winters before the show aired in early in 2008 and Dean Winters played the character throughout the series.
During Derek Reese's flashback scene in the future, we learn that Andy Goode was so ashamed of his involvement in creating Skynet that he began using the alias William "Billy" Wisher. William Wisher Jr. is a long-time collaborator of James Cameron, the creator/director of the Terminator films. Wisher also co-wrote the screenplay for Terminator 2: Judgment Day (1991).
In the pilot (#1.1) Cameron tells Sarah that she is from the year 2027. In "The Terminator" and "Terminator 2: Judgement Day" which took place before the TV series, Kyle Reese, the T-800, The T-101 and the T-1000 were from the year 2029.
Thomas Dekker portrayed a character on Heroes (2006) who was originally scripted to come out as gay. Dekker's agent demanded the script be changed so as to not jeopardise Dekker's chances of landing the role of John Connor.
Michelle Ryan whom was considered to play Cameron Phillips had starred in the short-lived reboot of the classic television series "Bionic Woman", which her character Jaime Sommers had her legs, her and her right eye replaced with robotic limbs, following a car accident.
In the backstory behind Sarah being obnoxious towards Cameron: Sarah distrusts Cameron and has trouble accepting Cameron (a female Terminator) is on her side, which she had the same problem with the T101 Terminator and also because she was jealous of Cameron because she felt that Cameron was a better protector and provider for John and that Cameron would replace her.
On the Facebook social network. A group called "Should Summer Glau have a guest role in an episode of Doctor Who?" was set up as an petition to get Summer Glau to appear in an episode of the long-running BBC science fiction series "Doctor Who". Summer Glau had been originally written to play the character of Jenny in The Doctor's Daughter (#4.6), but Georgia Moffett was cast in the role. Matt Smith whom played the Eleventh Doctor would go on to star as Tim in the 2015 reboot "Terminator: Genysis" and the former Doctor Who would also star opposite Lena Headey in "Pride and Prejudice and Zombies".
Throughout the series, John Connor does not cry excluding "Today is the Day: Part 2" (#2.18) when John breaks down and cries in Sarah's arms after confronting Jesse over using Riley to manipulate John into destroying his trust with Cameron, by making John and Sarah think Cameron was responsible for Riley's murder.
Sarah and John are both blamed for the death of Doctor Miles Bennett Dyson, the inventor of the neural-net processor that led to the development of Skynet. In "Terminator 2: Judgement Day", Miles Dyson was fatally shot by multiple SWAT team officers and succumbed to his bullet wounds and detonated a bomb that destroyed Cyberdyne headquarters, when he remained behind to allow Sarah, John and the T101 to escape.
2 years after the series was canceled, Lena Headey would star in the HBO series "Game of Thrones" opposite Emilia Clarke whom would play Sarah Connor in the 2015 reboot "Terminator Genisys". Jason Momoa whom played Khal Drogo in the first series, succeeded Arnold Schwarzenegger as Conan in the 2011 reboot of "Conan the Barbarian". Arnold Schwarzenegger played The Terminator in the films.
None of the film's after Terminator 2: Judgment Day (1991) are popular. After James Cameron left the series, the copyright passed through different hands, adding to the drop in quality. These films just vary what Cameron did without the same strength or imagination. Terminator Salvation (2009) was expected to reboot the series, but it was a box-office disappointment, so it was six years before the next film, Terminator Genisys (2015).
In the novelization of Terminator Salvation (2009), Skynet environments have typically red lighting. Skynet facilities, once up and running could carry out their programmed functions while the rest of the machines fought humanity and built new facilities, but they couldn't independently track intruders. Skynet will exhaust and starve its prisoners with an inhuman regard for them. Skynet's way of communication is all in codes and schematics, cold and disciplined, and the resistance had learned to interpret them.
Some of the Terminators that capture people are called Transporters; Transporters are only semi-sentient so they're not that bright. The brain of a Transporter is called a neural nexus. Transporters are easier to hack into than a Moto Terminator, which has freedom of action and can make decisions; a Transporter can do neither, only what it's told. Most people taken prisoner by the machines resigned themselves to death and the ones that didn't were taken away by the Terminators never to be seen again. Some followed their examples only to end the anticipation. The people in the camps wondered if it was a quick death because the machines were efficient, and not prone to sadism, except when extracting information. But they didn't resort to torture because it's deemed an inefficient allocation of resources rather than immoral. Some prisoners were known to go mad loudly or quietly, but the machines didn't care either way as long as they complied. T-600s tattoo prisoners with barcodes on their hands. Reese wondered if they were different for adults and children and did they have an expiration date or were altered in some way. The machines illuminate prisoners like an examination.
Terminators are designed for pursuit, and will take their time when killing someone, but they will scan and hunt their prey to the ends of the Earth because they believe termination to be a foregone conclusion. A Terminator will resume its mission if interrupted, as if nothing had happened. If a Terminator is damaged, the machines will send help if they think it's necessary, and will destroy a fellow Terminator if it's malfunction is impeding they're mission.
If John Connor were killed, the machines would scan his DNA too. A Terminator's directive to kill John overrode everything else. It would return to its ancillary programming once he was dead, and then back to primary.
The more mundane manufacturing activities of Skynet were below ground where the Terminators were assembled by automatons designed to build, not to hunt. They were powerful and single-minded but weren't programmed to deal with intruders. John Connor and Kyle Reese considered it a fascinating but horrifying place.
The resistance broadcasted with hidden towers scattered across the continent; they sent out encrypted signals that decrypted at the very end of the transmission. If they were traced by the machines they were rigged to self-destruct through an encryption timer. To prevent tracing, communications would not be completed until the very last moment. The resistance engineering staff assembled their own broadcast unit.
The resistance were losing more every month. But as the voice of the resistance, John Connor would rally them, whatever the end result may be, even though the words never came easily to him. John knew the resistance would persevere until all of Skynet's forces were destroyed.
Self-aware robotic killing machines are not too far from reality. The United Nations called for a ban on killer robots, for the fear that several countries are developing them and could threaten humanity. Even Stephen Hawking felt that the development of full artificial intelligence could one day spell the end of the human race.
Skynet's machines were immune to rain, but they preferred not to operate during heavy downpours; it complicated the electronic perception of their surroundings and could even interfere with their bipedal mobility.
HK's pick up movement and pursue it without needing daylight because they have infrared to close in on heat signatures. They have main batteries and are programmed to exterminate as well as get reports and scan histories on their targets. The shells of an assault rifle wouldn't damage an HK, it's too heavily armored but it would get its attention and try to find a clear line of fire. HK's have altitude and attitude control. Their Gatling guns could reduce a man to hamburger in less than a minute. The resistance always blow up an HK after deactivating it. HK's shoot guided missiles, even underwater and have sonar.
The resistance have RPG's (rocket propelled grenades) in their arsenal, as well as pistols, a 25mm semi-automatic grenade launcher with a box of thermobaric shells (that can stun or slow Terminators but not destroy them), a shotgun with sabot shells, grenades, plastic explosives, handguns, a Heckler & Koch MP5 sub machine gun, a 9mm Steyr, a Galil assault rifle and tanks in their armory (which the machines also use). They also have Blackhawk choppers, equipped with infra red tracking, mini guns, napalm and heavy-caliber machine guns; they use trackers to home in on members with a rescue party.
Another form of Terminator is a Hydrobot, something designed to operate in the water. If it can't carry out its program, it thrashes about. Although Hydrobots are eyeless, they had a host of other sensors and razor metal jaws to clamp down and chew through an enemy, even choppers. Because they're only 4ft in length, they attack in numbers to bring down an enemy, and they're tough outer shell repels most bullets. Hydrobots are useless on land, so the best they could do is fling themselves out the water at someone.
The machines protecting Skynet Central were programmed to obliterate anything carbon-based that enters the zone; it was also protected by an enormous wall, integrated gun emplacements and sensors. Skynet didn't need sentries, ambulatory patrols or razor wire; the high-powered instant reactive automated cannons mounted in gimbal turrets detect and annihilate anything organic on the perimeter; machines could pass that continuously by broadcasting their assigned ID to recognized Skynet protocols. Skynet Central had self-aware loaders, welders, trucks, tiny scavenging devices, multi-wheeled clean-up containers, etc. They all shared the same narrow purpose. T-600s patrol the exterior. Skynet Central has a jungle of antennae on the roof. The ventilation shafts generate so much heat, even the machines need fresh air. The top floor is the command centre, that has more processing power than the planet ever had. Skynet Central uses a series of lights to show if everything is working right; green or white meant yes, red and yellow meant no, but that was rare. Skynet Central has a database on all the prisoners. Skynet Central didn't have much in the way of sentries on patrol because the machines thought no-one could get past the outer fortifications so wouldn't waste resources. There are inactive machines at Skynet Central like excavators or delivery trucks, mindless servants that lacked sentience and couldn't make decisions on their own without what Skynet programmed into them. Skynet Central was designed to provide easy access from T-1's to larger wheeled machinery. It was their own constructed world, doorless, clean, polished, functional and nothing human. The controls st Skynet Central are familiar and straightforward, a standard Skynet design. The door locks need a disruptor to short them out.
Along with the release of Terminator Salvation (2009), there was Terminator Salvation: The End Begins, a game where you play as John Connor, leading the Resistance against Skynet. Out in May 2009, it was available for Xbox 360, Xbox Live and PlayStation 3.
After the release of Terminator Genisys (2015), Arnold Schwarzenegger said James Cameron "did an extraordinary job creating that character (The Terminator) and whole phenomenon. I never thought we would do a sequel, catchphrases like "I'll be back" or "Hasta la vista, baby" would catch on and be repeated or think that 30yrs later I would be asked to come back to a franchise like this playing The Terminator, unlike Batman or James Bond."
Emilia Clarke became a huge fan of the Terminator franchise after being forced to watch the first two films when she was 7-8yrs old by her 9yr old brother; she later portrayed Sarah Connor in Terminator Genisys (2015).
Peter Mensah whom played General Perry in Terminator: The Sarah Connor Chronicles: Alpine Fields (2008) and Terminator: The Sarah Connor Chronicles: Dungeons and Dragons (2008) had starred opposite Lena Headey in 300 (2006) as Messenger and would go on to star in Avatar (2009) which was directed by Terminator creator James Cameron and he would go on to star as Oenomaus in the hit television series Spartacus: Blood and Sand (2010) which is based upon the history of the Thracian gladiator Spartacus whom led slaves and gladiators into rebellion against Rome. In this series and in the Terminator films, John Connor leads the human resistance against Skynet.
In a scene that was cut from the pilot (#1.1) Sarah tells Cameron about a recurring dream she had about protecting John, but dies every time and cries talking about, when Cameron removes a bullets from Sarah's torso.
Lena Headey's future "Game of Thrones" co-star Peter Dinklage and Emilia Clarke would later star in science fiction films about post-apocalyptic futures, robots and time travel: Peter Dinklage would star as Bolivar Trask in "X-Men: Days of Future Past" and Emilia Clarke would star as Sarah Connor in "Terminator: Genisys" and would become the 3rd actress to play Sarah Connor, played in this series by Lena Headey and played in the "The Terminator" and "Terminator 2: Judgment Day" by Linda Hamilton.
Catherine Weaver (Shirley Manson) is a female liquid metal T1000 Terminator from the future, has a Scottish accent and had red hair. When the series premiered in 2008, British comedian and actress Catherine Tate joined the long running British time travel series "Doctor Who" as Donna Noble, the redheaded companion of the tenth incarnation of the extra terrestrial time traveler The Doctor (David Tennant). Later in that series, The Doctor would later have a Scottish companion with red hair called Amy Pond (Karen Gillan), David Tennant whom played The Doctor is from Scotland.
The resistance have an abandoned missile silo to imprison Terminators, the interior is very high up. The resistance brig was used usually for sleeping off too much booze, soldiers who fight amongst themselves or to settle gambling debts from adjoining cells.
Another machine in the future is an Aerostat, an independently guided Skynet tracking device; it transmits information and scans potential victims but will wait before opening fire. Another is a flying Harvester, which has assorted sensors, both the normal and infrared visual spectrums and ultraviolet. It also has great range to fire at something with more than one weapon. Harvesters place prisoners into Transporters; valuable specimens are placed in the forward section. Harvesters have CPU's too. There are also Moto-Terminators, bikes that chase their victims that go much faster than a Harvester; their responses are faster than any human driver, and they have a very tough outer shell. Moto-Terminators can travel up to 200mph; they home in on sounds associated with human presence. Music means nothing to a Moto because it carried no digital instructions but it could lead them to a human and it was much faster than a human. But although it had a tough exterior, it's innards were much more vulnerable to reprogramming. Motos are not designed to be ridden but can be with difficulty if they're reprogrammed. Motos can do wheelies no human ever could. Motos are mindless and will even go off a bridge to follow their programming.
San Francisco still exists in the future. Some of Skynet Central made use of the ruins of greater San Francisco; there are self-aware, automated bulldozers that remake the city in their own image and according to Skynet's plan (perhaps the buildings will become self-aware too). The machines were rebuilding San Francisco as an industrial fortress for Skynet but they had blown up the Golden Gate Bridge. Because it's gone, there are no humans, and Skynet won't waste resources to patrol it. Skynet had placed movement sensitive gun turrets at the end of the bridge that wait before opening fire. John Connor still felt San Francisco had beauty, just not as much of it.
In the future, one of the advantages of living outside of a major city away from Skynet's control is that groups of humans had managed to hoard away packaged and canned foods, as well as vacuum-sealed loaves of bread, cans of beer, soda, water and fresh vegetables. It was more food than Reese had seen in his life; Reese hadn't tasted ice cream in years. Apples are rare in the future; the resistance tried to keep the base supplied with food, clothing and medical supplies, but fresh fruit was a luxury. There were still orchards but half wild and overgrown that still provided fruit in season carefully picked by civilians.
When the machines brought prisoners to the camps, they were too neat and efficient to be a slaughterhouse but there were bits and pieces of people hung from the ceiling, viscous liquids in tubes, electrically stimulated arms, legs, organs and torsos, like specimens to be studied. John Connor wanted to help the people being experimented on by putting them out of their misery; some of them were kept in a gelatinous preservative. The machines used disinfectant so the specimens they were studying wouldn't become contaminated. When studying humans, automatic vivisectors are emotionless when dealing with a screaming test subject.
Although the machines believed themselves superior to humans, they had learned not to underestimate them; they maintained a constant vigil for any escape attempts, and the mere presence of a T-600 would deter any; they're programmed to respond to any deviation to the norm, like an empty lift shaft.
A Terminator's sensors can magnify and analyze substances, like C4, but if it encountered some without a detonator it would consider it useless. If a Terminator analyses something new, it adds the data to its individual database.
A T-600 is more powerful than quick; it can't observe, evaluate and react all at once. It does have one vulnerable spot, an exposed space at the base of the neck. If attacked there, it loses motor control.
In the novelization of Terminator Salvation (2009), unrelenting combat had aged some of the troops beyond their years, but still they persisted. Someone called Chris was in the Resistance. Some of the soldiers call John Connor a class-A terrorist. Most of the resistance were good at killing, but only a few were good at the technical stuff. Connor is nearly always solemn, he had learned to stay alive by moving fast, and anyone not made of metal and circuitry was a companion to him. His calm under fire was both reassuring and unnerving to the resistance. John didn't feel much contentment anymore and neither did anyone else in the resistance. He felt alone most of the time and sometimes liked to be left alone. John wondered if Skynet had developed a macabre sense of humor. John played back several of Sarah Connor's tapes, memorizing them so from her advice he could learn how to fight back against the machines. He considered them a part of him, just as she was, but he missed her for her confidence and assurance that humanity would win and Skynet would be defeated, even when things seemed hopeless. John lapsed more and more into depression as the war raged on but he could shake off melancholy and become all business again when the need arose. The war had given John permanent frown lines on his forehead. John didn't back away from anything. At the base, John's orders were followed more than anyone else's. John was used to not being listened to; he could never understand why. John only understood the rules on the outside because he made them. John always managed to bounce back strongly, even in the darkest moments. John's hands were scarred. Not much could unsettle John in the future but the people herded to their deaths did. John had learned that the best way to beat the machines was to turn their efficiency against them. John considered the possibility that the machines may go crazy and start shooting at one another. John tried to blow up Skynet Central.
Not the first time Shirley Manson has played a robot. In the music video of "The World is Not Enough" by Garbage, she played a robot replica of herself whom the real Shirley Manson killed and took her place. In the series, Catherine Weaver (Manson), a T-1001 liquid metal Terminator, replaced the real Catherine Weaver, the CEO of Zeira Corporation.
If a third season had been produced it would have been impossible for John Connor to aid his future self. In the final episode of season two, Weaver and he travel to the future, where they encounter resistance fighters whom have no knowledge of John Connor. This fits as John travelled forward, altering the already convoluted Terminator timeline, meaning he was no longer present to grow up in the aftermath of Judgement Day and able to lead humanity as a grown man. A third season would have had to explore the differences an initially Connorless future would hold.
